You can move/hide the icons by highlighting the icon, pressing the menu button, and clicking Hide or Move (if you select Move, you then use the trackball to move the icon where you want it and then click the trackball).

For the email/text thing, go into your Messages app, press Menu, then Options, then General Options. For SMS and Email Inboxes, set it to Separate.
